i have written a script that saves the attachments from all unread messages from a gmail account to my hard drive I am doing this by printing the source code of the attachments into a pdf file created during the scripts run. But all of the PDF files are almost completely corrupt (for some reason 1 in around 20 pages in each file are fine the rest are completely blank) Is there another way to do this or a way to programmatically fix the pdf files I have been at this for days and I i still haven't figured out so any help is appreciated thanks in advance.
